A kind of the technical solution of the utility model are as follows: gasbag-type clamping device, it is characterised in that: including chuck body 18,
Air bag 19, positioning baffle ring 20 and ring flange 26；Chuck body 18 is fixed on ring flange 26, and air bag 19 is mounted on chuck body
On the small-diameter circular cylinder of 18 fronts, each connection pipe fitting of air bag 19 is put into the corresponding location hole of chuck body, positioning
Baffle ring 20 is mounted on 18 front end of chuck body.
Safety valve 21, rapid aeration valve 23 be mounted in chuck body 18 in corresponding location hole and and air bag it is corresponding
Pipe fitting be connected, the quick-changing-pipe pipe-adoptor 22 with check valve from positioning baffle ring 20 location hole in pass through and and air bag 19 pipe fitting
It is connected.
Ring flange 26 is connect with lathe.
24 sets of workpiece outside air bag, are mounted on the positioning table of chuck body 18 and the positioning surface of positioning baffle ring 20.
Quick-changing-pipe pipe-adoptor 22 with check valve inflates air bag 19.
The air pressure of safety valve setting air bag 19.
24 stretching of workpiece is realized the clamping to workpiece 24, processing under the resilient force of air bag 19 after inflation
Non-ferrous metal thin-wall workpiece.
The workpiece 2mm-5mm.
The utility model has the advantages that the inner/outer hole that the utility model is applied to degree of precision non-ferrous metal thin-wall workpiece is processed, inflating air

The shape finishing step of batch high-precision workpiece.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
To keep the purpose of this utility model, content and advantage clearer, specific embodiment of the present utility model is made
It is described in further detail.
The utility model provides a kind of gasbag-type clamping device, including chuck body 18, air bag 19, positioning baffle ring 20, peace
Full valve 21, the quick-changing-pipe pipe-adoptor 22 with check valve, rapid-release valve 23, screw 25 and ring flange 26；
Chuck body 18 is fixed on lathe upper flange plate 26 by screw 25, air bag 19 in chuck body 18,
Each connection pipe fitting of air bag 19 is put into the corresponding location hole of chuck body, and positioning baffle ring 20 is mounted on chuck body 18
On, safety valve 21, rapid aeration valve 23 are mounted in chuck body 18 in corresponding location hole and connect with the corresponding pipe of air bag
Head is connected, and the quick-changing-pipe pipe-adoptor 22 with check valve passes through from the location hole of positioning baffle ring 20 and is connected with 19 pipe fitting of air bag,
Check that each connector carries out air tightness test, by workpiece 24 mounted in the positioning surface of the positioning table of chuck body 18 and positioning baffle ring 20
On, it realizes the positioning to thin-wall workpiece, air bag 19 is inflated by the quick-changing-pipe pipe-adoptor 22 with check valve, passes through safety valve
The air pressure for setting air bag 19 is realized 24 stretching of workpiece to workpiece under the resilient force of air bag 19 after inflation
Non-ferrous metal thin-wall workpiece is processed in 24 clamping.Workpiece 24 is detected, gasbag pressure is adjusted, is pulled after work pieces process quick
23 handle of vent valve, deflates to air bag 19, after reaching drawing requirement, unloads workpiece 24, after detection is qualified, starts batch and adds
Work.
The inner/outer hole that the present invention is applied to degree of precision non-ferrous metal thin-wall workpiece is processed, and air bag itself has bullet
Property, air bag clamping force uniformly acts on non-ferrous metal thin-wall workpiece, and the size of air bag elastic force can use safety valve setting,
The size of air bag clamping force is adjusted according to the wall thickness and strength conditions of non-ferrous metal thin-wall workpiece, grip device loader
Part is convenient, solves the processing problem of degree of precision non-ferrous metal thin-wall workpiece.
Within machining accuracy and geometric tolerance are up to 0.02mm, the high-volume high-precision work suitable for wall thickness 2mm-5mm
The shape finishing step of part.
Air bag itself has elasticity, and generated clamping force stepless action is in the circumferential surface or axial end face for clamping workpiece
On, generated clamping force is less than the deformation force of workpiece, and clamping force should be greater than cutting force.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
